Case Report

A 44-year-old African-American woman presented with
complaints of worsening dyspnea and chest discomfort
for several months

Review of systems revealed long-standing dyspnea on
exertion, orthopnea, and paroxysmal nocturnal
dyspnea.

Physical exam was significant for JVD, decreased
breath sounds in the lung bases, tachycardia, and lower
extremity edema to the knees. Notably, the exam was
lacking rales and an S3 gallop.

Differential Diagnosis?
Chest radiograph revealed an enlarged cardiac sillouette and bilateral
pleural effusions (Figure 1).
Bedside echocardiography revealed a pericardial effusion
(Figure 2).
Data



Laboratory findings included a macrocytic anemia
(MCV 114.6 fL, HCT 22.2%) with a high corrected
reticulocyte count (14.5) and normal B12 and folate
levels.
Auto-immune hemolytic anemia was confirmed by a
decreased haptoglobin (<14 mg/dL), an elevated LDH
(1411 U/L), and the detection of a warm IgG autoantibody.
ANA testing revealed a 160 titer and an anti-DNA DS
level of 101 IU. Right heart catheterization revealed
tamponade physiology.
Discussion

This case represents a rare presentation in a patient with SLE.

The patient's symptoms were secondary to both tamponade and hemolytic
anemia, perhaps two of the most morbid of the diagnostic criteria.

The eventual diagnosis may have been delayed were it not for careful
attention to the physical exam and prompt diagnostic testing to validate
those findings.

Standard treatment for congestive heart failure based solely on reported
symptoms would have greatly increased her morbidity, and could have
been fatal.

This case emphasizes the importance that our history AND physical
examinations guide our diagnostic and therapeutic measures.

SLE: Demographics

Affects .5 million (.2%) vs 1.5 million (.6%) of US
population (epidemiologic vs LFA random digit dialing
telephone survey)

Female:Male ratio of 10:1


Closer to 2:1 during childhood and after menopause, suggesting
hormonal influence
Disease in males is often more severe

70% of SLE: females between ages 15-45

African American to Caucasian ratio 3:1

Highest prevalence in Afro-Caribbean females 1:250
Demographics

Genetic factors HLA-A1, B8, Dr3 - C4A null genes - Fc
receptor polymorphisms -gene linked to chromosome 1

Environmental factors - Concordance for monozygotic twins
is 30% (70% of genetically identical twins will not share the
disease)

Child of SLE mother risk of SLE 1:15 (7%)

ANA positive in 5-20% of population. 10 times more likely
to have false positive ANA than disease
Null alleles that cause a deficiency of one of the
early complement components — C1q, C2, or C4
— are a strong risk factor for lupus.


Family studies have identified genes that are more
likely to occur in patients with lupus than in their
healthy relatives.
Many of these genes encode components
of the immune system.

The anti-phospholipid Ab syndrome (APS) is vascular
thrombosis and/or pregnancy morbidity developing in
persistently anti-phospholipid antibody (aPL)-positive
individuals.

The most commonly used aPL tests are the lupus
anticoagulant test, the anti-cardiolipin antibody ELISA,
and/or the anti- b2-glycoprotein I ELISA.

APS is present if more than 1 clinical and 1 lab criteria met

Goals:
To induce remission with a stringent

GC and a cytotoxic drug, given for short period of
time (3-12 mo, induction phase)
 To achieve a response and
 To maintain this response in the long term by
prescribing a safer immunosuppressive Rx for a
longer period (5-10yrs, maintenance phase)

Definition of Response, Nephritis



Fair clinical response: 50% reduction of
proteinuria and stabilization of renal function
VS:
Complete remission – absence of proteinuria

Role of the Primary Care Physician
Assessments to Order
Initial: CBC, SMA-20, ANA,
dsDNA, C3/C4, ESR, CRP, UA,
Rheumatoid Factor, Vit D 25OH
If possible overlap or other:
centromere, Scl-70, CPK,
aldolase
If Signficant Arthritis: XRAYS
If prior diagnosis of SLE,
patient seeking continuation
of care: Subserologies: Ro, La,
Sm, RNP, LAC, Cardiolipin Ab
Reasons for Referral to Rheumatology







To confirm a diagnosis
To assess disease activity and severity
To provide general disease management
To manage uncontrolled disease
To manage organ involvement or lifethreatening disease
To manage/prevent treatment toxicities
Other circumstances: APLS, pregnancy, surgery
Follow Up Visits



Frequency depends on activity, severity, and
extent of SLE, response to treatment, type of
treatment, need for toxicity monitoring
At routine visits, CBC, SMA, UA should be
checked, even in patients with previously normal
values
Patients with known renal disease should also
have either 24 hour urine or spot
protein/creatinine checked every 6-8 weeks
Follow Up
Active disease can be diagnosed by
Assessment of clinical features such as rash, arthritis,
serositis, etc
 Laboratory features: dsDNA Ab, complement levels,
CBC
 Imaging: CXR, ECHO, etc

Severe or Life Threatening Complications
Monitoring for Specific Medications


Patients on chronic steroid therapy must also be
on Calcium/Vitamin D
Anticipate the need for possible bisphosphonate
therapy, check DEXA
Role of the Primary Care Physician



Patients may have more frequent access to their
primary care physician as compared to Rheum
or Renal Services
Understand the importance of disease severity:
lupus and it’s treatments are highly toxic and
clinical status can decline rapidly
Do not hesitate to call the Rheumatology
Consult Service when initiating work-up or to
discuss continued care
